Create a finished vertical 3:4 festival poster for a daytime outdoor music festival. All typography must be sharply legible and spelled exactly as quoted. At the top, a small centered uppercase line: "MUSIC • ART • OPEN AIR" in compact white geometric sans lettering. The dominant headline occupies the central 60% of the poster on two lines: "COLOR" then "BURST 2026". Custom bold rounded display lettering with thick, spherically convex inflated strokes, balloon-like counters, hemisphere terminals, and ultra-glossy candy lacquer. EACH INDIVIDUAL LETTER contains its own complete vertical ROYGBIV gradient: red at its top edge, orange upper zone, yellow through green in the middle, blue and indigo below, violet at the bottom. Do not spread one gradient across the word; every character is a full rainbow. Add crisp near-white circular specular highlights at each letter apex, subtle translucent internal reflections, and a narrow white rim light. Make “2026” slightly smaller but built in the same lettering. Below headline, centered: "SEPTEMBER 12–13 • RIVERSIDE PARK" in bold white uppercase sans, then "2 DAYS · 4 STAGES · 40+ ARTISTS" in smaller white uppercase sans. At the bottom, a white rounded ticket-strip badge reading "TICKETS ON SALE NOW" in dark violet uppercase, and beneath it "COLORBURSTFEST.COM" in small white uppercase. Scene: bright blue summer sky transitioning to a warm amber-pink horizon, shallow depth of field. Behind the headline, soft bokeh festival string lights in red, orange, yellow, green, blue and violet; sparse multicolor confetti streamers, translucent soap bubbles, and a low silhouette of a festival stage and crowd along the bottom edge. Strong warm sunlight from upper-right creates bright specular highlights and light flares on the inflated letters. Keep the center text unobstructed. Full chroma color, clean contemporary event key art, print-poster clarity, no extra words, no logos, no watermark.
